Genuine Haltech gear, stocked and supported by the team at Willys Workshop, diesel and performance specialists in Brisbane and the Sunshine Coast.
Overview
VCU OVERVIEW
Nexus R5 is Haltech’s flagship product combining the functionality of a power distribution module, a data logger, a dual channel wideband controller and a state-of-the art engine management system in one powerful device we call a VCU (Vehicle Control Unit).
4 x 25A (continuous) push-pull PWM capable (5 kHz) outputs (for power to injectors / coils, transbrake, thermofan, fuel pump)
12 x 8A (continuous) high side outputs (low speed PWM, 200 Hz) outputs (power to sensors, NOS solenoids, etc)
18 x peak/hold injector drivers (can be used as low side drive outputs)
12 x low current ignition outputs (can be used as low side drive outputs)
8 x low side drive outputs, PWM capable (DPOs)
4 x push-pull / h-bridge outputs (8A, PWM capable), eg for electronic throttle
